The main alloying elements of 8011 aluminum strip are silicon (Si) and iron (Fe), with a silicon content of 0.5 – 0.9% and an iron content of 0.6 – 1.0%. The remaining is mainly aluminum, along with trace amounts of other elements such as copper, magnesium, and manganese.
| Element | Symbol | Content Range |
|---|---|---|
| Silicon | Si | 0.5 – 0.9% |
| Iron | Fe | 0.6 – 1.0% |
| Aluminum & Others | Al + trace | Balance (Cu, Mg, Mn...) |
In the O temper (fully annealed), the mechanical properties are as follows:
| Property | Value (O Temper) |
|---|---|
| Tensile Strength | 70 – 110 MPa |
| Yield Strength | 30 – 50 MPa |
| Elongation | 20 – 40% |
These properties make it have good formability and ductility, which is conducive to the processing and manufacturing of pipes.
The thickness of 8011 aluminum strip for pipes is usually in the range of 0.1 – 1.0 mm, and the width can be 10 – 300 mm.
| Parameter | Range | Tolerance |
|---|---|---|
| Thickness | 0.1 – 1.0 mm | e.g. ±0.02 mm at 0.21 mm |
| Width | 10 – 300 mm | ±0.2 mm |
